No SSL Decyrption with content Inspection Enabled.

L1 Bithead

Hi All,

 

I have enabled the content inspection features like URL filtering\Antivirus\Wildfire analysis etc.

However SSL decryption is not enabled.

 

Could someone please let me know that content inspection features really worth if SSL decryption is not enabled.

Hi @manninegi1985 ,

 

In my opinion, your AV, VP, and FB profiles will only work on around 10% of your traffic without SSL decryption.  The 2 biggest attack vectors in companies are web and email.  Almost all email traffic and 90% of web traffic is encrypted.  If you want the security features (that you pay for) to be applied to all traffic, then you should enable decryption.

 

Decryption can break a small number of sites.  Be prepared to make exceptions.  The Day 1 Configuration has an excellent example of a no-decrypt policy.
